摘要

以典型斜齿轮副为对象，基于接触有限元法，先模拟其准静态啮合过程并求解啮合刚度，并与国家标准偏差值进行了对比，证明了分析方法的正确性.再模拟其动态啮合过程，通过对啮合力响应进行频谱分析识别出扭转振动的固有频率，并与绘制频响曲线的识别结果一致.在此基础上，数值模拟了该齿轮副扭转共振的发生、发展和稳定过程，定量分析了共振状态下的典型动力学参数响应.结果表明：脱离啮合现象的发生使齿轮副的啮合冲击更为显著，共振状态下的最大应力值相比啮合频率为3000Hz时增大了20%.

Abstract

To simulate the continuous engagement of gear pair under resonance state

the contact finite element method was described and proved to be reasonable by comparing the meshing stiffness with national standard. The research object was a helical involute gear pair

the natural frequency of torsional vibration was got by spectral analysis method and frequency response analysis method. The occurrence

development and steady state of gear pairs torsional resonance were simulated numerically

and several dynamic parameters were analyzed quantitatively. The results showed that

the separation during the meshing process made the effect of meshing impact more significant. The maximum vonMises stress increased by 20% compared with the value when the meshing frequency was 3000Hz.
